Maybe my screen's not big enough, but I don't see a headstock repair. The wooden(?) block is interesting. I also suspect a Strat-type tremolo was added and removed in the past. A slight red flag that none of the pics focuses on that area, though. I'd certainly want some close ups of both the back and the front showing the block before I'd consider this one. Otherwise a cool old Alembic that you don't see everyday.
Bill, tgo
